Use CLE from angr project to load dynamically linked executable

[erdnaxe]

This patch proposes to use CLE as a dynamic library loader.

This enables users to load dynamically linked executable. This greatly simplifies the simulation of programs linked with glibc as one would usually only need to hook calloc, malloc and free functions.

To make this patch fully usable, https://github.com/Ledger-Donjon/rainbow/pull/51 is needed.

Thank you very much, very useful. Do you think cle could replace the other wonky loaders (ELF, PE, ... )? Would be a nice cleanup.

• For ELF loader, CLE seems to handle more cases than current elfloader.
• Same for PE loader.
• As far as I know, CLE does not handle a hex loader.

Would it be okay if I propose to drop peloader and elfloader in this pull request?

Yes you can :)
